Abstract
The paper deals with important, different views on the old glaciation of the Caucasus based on the literary sources and the latest data obtained through the expeditions. Our researches are mostly of complex character where petrographic, palynological and paleontological methods are widely used. The petrographic method allowed us to connect block debris of the moraine with the main centers and to determine the directions of the glaciers movement and their distribution boundaries. The palynological method was used to determine the genesis of loose sediments considered as moraines and their sedimentation conditions. The palynological spectrum of deposits shows that they are river sediments and their sedimentation took place under humid, moderately warm climate conditions that is not associated with glaciation.
